Hi, I'm using oprofile to do some performance measurement and it definitely is a great tool! But during using, I have one suggestion. We could know how many relative cpu percentage the program used. But we can't get the absolute cpu usage of the program. Without the absolute cpu usage, I can't compare the whole system improvement between two different deliveries. Could you add this one in new release or kindly tell me which file I could modify by myself? Thank you! BR//Jubing LI |

Are you looking for comparison between two sets of oprofile data like: http://oprofile.sourceforge.net/doc/opreport.html#opreport-diff -Will |
